I picked the 2 best “foam brush chemicals” and took 25 fl oz of each of the diluted chemical and added 5 gallons of water. The winners were 3) Dis™h Detergent Original Scent (dish cleaner 50 ounces) and 4) Perfect 10 Black Currant Bodywash (bodywash for your body 25 ounces). I lost the pictures for number 4 but number 3 was the best the dish detergent.
To test the chemicals I made a foam brush setup and even used a “super foamer” (second photo). I hooked up the yellow air compressor to a large broken air compressor in my garage. I also have a bucket full of water to clear out the lines. I used a screw driver to weigh down the chemical line.
